How to Grade Your 1999 Quarter at Home
Correctly identifying coin grades helps collectors avoid bad deals. Professional services grade coins using the Sheldon seventy-point scale. You can learn basic grading steps using these descriptions.
MS60
- No circulation wear
- Weak metal luster
- Many small marks
An MS60 coin has zero wear from pocket use but looks dull. The coin surface shows many tiny scratches. These coins value $0.50 to $1.00.
MS63
- Mint luster present
- Fewer surface marks
- Good overall strike
An MS63 coin shows nice original shine on the metal. Some small scratches exist on the main design details. These coins value $1.00 to $1.50.
MS65
- Strong mint luster
- Very few light scratches
- Sharp design details
An MS65 coin looks beautiful and bright to the eye. Only a few minor marks are visible under magnification. These coins value $2.00 to $3.50.
MS67
- Outstanding metal luster
- Almost perfect surfaces
- Excellent strike detail
An MS67 coin has zero eye-visible marks. The strike is fully detailed, showing every leaf or hair line clearly. These coins value $15.00 to $110.00 depending on the state.
Pro Coin Storage Mistakes That Lower Market Value
Incorrect coin storage can destroy coin value instantly. Many collectors lose hundreds of dollars due to easy mistakes.
- PVC plastic holders
- Paper envelopes
- Acidic boxes
- Glass jars
- Open drawers
PVC plastic coin flips damage coin surfaces over time. The plastic chemical leaks onto the copper-nickel metal, creating green slime. This chemical damage reduces a $100 coin value to zero.
Cleaned coins lose about 50% to 80% of their market value. Never clean a dirty coin using metal polish or soap. Experienced coin buyers spot cleaned coins immediately. A cleaned MS67 coin loses its value, dropping to MS60 price levels.
Store valuable coins in hard plastic coin capsules. Keep your collection in dry rooms with stable temperature. Moisture creates ugly spots on copper-nickel surfaces, ruining the original mint luster.
